Getting things ready to mount back to boat transom, the grease tube to the gimbal bearing fell out. I was able to push it back in but that got me thinking of how water actually got in the bellows in the first place (separate problem from water leaking behind transom shield).
I've read the link in the Adults Only section about where a member tapped the hole out and installed a 45* elbow fitting. Nervous about tapping and potentially (my luck) screwing it up and trashing a shield. Still, while i have everything off the boat now is the time to do it so i don't have to do it later. Seems to be a weak link for a pretty important area. The replacement bearing i have is not sealed (new to this so wasn't aware there's two kinds).
While the pics are good, i wish it showed more of stbd side. What i'm trying to determine is how close to the exterior of the bearing cavity it is. that would give me a better idea of when i should stop tapping it out. Basically, a peace of mind kind of thing.
I plan on using a tapered tap so not as much torque needed to start. Unfortunately it doesn't appears McMaster-Carr offers single 1/8-27 tap anymore; you have to buy a kit.
Has anyone else done this 'mod' for the grease fitting and, if so, any additional tips or suggestions before i tackle this Right now, i have the tube put back in and coated the last 1/4 of it with permatex #3 then tapped it into the bearing cavity hole with a mallet by hitting the existing fitting. But, my OCD is killing me so I just want to eliminate this as a future problem altogether.
Thanks!
